Everyone knows that in the paving operation process, it is necessary to comprehensively consider many influencing factors in order to achieve high-quality paving.

如果熨平板前料頭過大，且溫度過低，會對預(yù)壓實和熨平板浮動帶來不良影響。

If the material head in front of the ironing plate is too large and the temperature is too low, it will have a negative impact on pre compaction and floating of the ironing plate.

熨平板前保持恒量的料頭有利于熨平板的浮動。

Maintaining a constant amount of material in front of the ironing plate is beneficial for the perfect float of the ironing plate.

攤鋪層越厚，熨平板所受承托力越強(qiáng)。

The thicker the paving layer, the stronger the supporting force on the screed.

按比例控制的刮板輸料器和螺旋分料器，為在熨平板前保留理想數(shù)量的料頭提供了可能。

The proportional control of the scraper conveyor and spiral distributor provides the possibility of retaining the desired number of material heads before the ironing plate.

夯錘行程及夯錘速度

Ram stroke and hammer speed

夯錘行程的幅度及夯錘速度是影響攤鋪料預(yù)壓實與熨平板浮動的重要影響因素。

The amplitude of the ram stroke and the ram speed are important factors affecting the pre compaction of paving materials and the floating of the screed.

福格勒熨平板的夯錘行程可以設(shè)定為不同長度。夯錘的行程越長，其預(yù)壓實效果和壓實深度越理想。因此，應(yīng)使夯錘行程的設(shè)定與攤鋪厚度相匹配，以獲得**正向攤鋪仰角。如果夯錘行程的相對攤鋪厚度設(shè)定過長，會導(dǎo)致熨平板負(fù)仰角，從而導(dǎo)致攤鋪層出現(xiàn)裂紋，甚出現(xiàn)攤鋪層起伏不平。夯錘速度

The hammer stroke of the Fogler ironing plate can be set to different lengths. The longer the stroke of the rammer, the more ideal its pre compaction effect and compaction depth are. Therefore, the setting of the rammer stroke should be matched with the paving thickness to obtain a positive paving elevation angle. If the relative paving thickness of the rammer stroke is set too long, it will lead to a negative elevation angle of the screed, resulting in cracks in the paving layer and even uneven paving layer. Hammer speed

夯錘速度與攤鋪機(jī)行駛速度是否匹配，會對攤鋪層的預(yù)壓實帶來巨大影響。這意味著必須調(diào)整夯錘速度使之與攤鋪機(jī)行走速度匹配，或者改變攤鋪機(jī)行走速度與夯錘速度匹配。但理想的比例關(guān)系很難確定，要根據(jù)具體工況進(jìn)行必要調(diào)節(jié)，使熨平板攤鋪仰角盡可能小，從而降低攤鋪料對熨平板底板的磨損。

Whether the speed of the rammer matches the driving speed of the paver will have a significant impact on the pre compaction of the paving layer. This means that the speed of the compactor must be adjusted to match the walking speed of the paver, or the walking speed of the paver must be changed to match the speed of the compactor. However, the ideal proportional relationship is difficult to determine, and necessary adjustments should be made according to the specific working conditions to minimize the elevation angle of the screed paving, thereby reducing the wear of the paving material on the bottom plate of the screed.

熨平板硬度

Screed hardness

當(dāng)對熨平板攤鋪仰角做大幅度改變或單側(cè)改變時，可能會導(dǎo)致熨平板出現(xiàn)扭轉(zhuǎn)。

When making significant or unilateral changes to the paving elevation of the screed, it may cause the screed to twist.

熨平板防爬鎖

Screed anti creep lock

熨平板鎖定是熨平板浮動模式下攤鋪機(jī)停機(jī)后，開始繼續(xù)行走前執(zhí)行的短暫鎖定動作。此時有大約30 bar壓力作用于熨平板升降油缸的活塞端，這樣可避免重新開始工作時由于熨平板被抬升而造成的攤鋪面凸起。

Screed locking is a brief locking action performed after the paver stops in the floating mode of the screed and before continuing to walk. At this point, approximately 30 bar of pressure is applied to the piston end of the ironing plate lifting cylinder, which can avoid the protrusion of the paving surface caused by the ironing plate being lifted when starting work again.

攤鋪速度攤鋪速度決定了攤鋪面的預(yù)壓實效果。

The paving speed determines the pre compaction effect of the paving surface.

攤鋪速度和熨平板前的料頭應(yīng)相互匹配。

The paving speed and the material head in front of the screed should match each other.

當(dāng)進(jìn)行高速攤鋪時，對攤鋪料的消耗量很大，因此應(yīng)確保攤鋪料的及時供應(yīng)。攤鋪速度應(yīng)控制在料車能夠持續(xù)不間斷地為攤鋪機(jī)供料的范圍內(nèi)。

When high-speed paving is carried out, the consumption of paving materials is high, so timely supply of paving materials should be ensured. The paving speed should be controlled within the range where the hopper truck can continuously supply the paver with materials.

攤鋪速度對攤鋪層的預(yù)壓實有著關(guān)重要的影響。應(yīng)盡可能保持小攤鋪仰角，這樣可避免出現(xiàn)攤鋪凸起，實現(xiàn)**預(yù)壓實效果。而攤鋪機(jī)速度與攤鋪仰角成正比，因此應(yīng)將攤鋪速度控制在小仰角攤鋪的范圍內(nèi)。

The paving speed has a crucial impact on the pre compaction of the paving layer. Try to maintain a small paving elevation angle as much as possible to avoid paving protrusions and achieve a pre compaction effect. The speed of the paver is directly proportional to the paving elevation, so the paving speed should be controlled within the range of small elevation paving.

振動器頻率

Vibrator frequency

當(dāng)進(jìn)行厚層攤鋪時，振動器頻率會對預(yù)壓實效果有一定影響。由于磨耗層需要是結(jié)構(gòu)致密、平整的攤鋪面，振動器的頻率對磨耗層攤鋪更為重要。壓力梁頻率與壓力壓力梁在脈沖液壓流的驅(qū)動下上下擺動。此脈沖由安裝在熨平板上的旋轉(zhuǎn)分配閥產(chǎn)生，其頻率在 58 到 68 Hz之間。液壓油缸驅(qū)動壓力梁作用于整個攤鋪寬度。當(dāng)脈沖結(jié)束后，壓力梁在反向彈簧的推動下返回其原始位置。作用在壓力梁上的脈沖壓力大小決定壓力梁的行程。

When conducting thick layer paving, the frequency of the vibrator will have a certain impact on the pre compaction effect. Due to the need for a dense and flat paving surface for the wearing layer, the frequency of the vibrator is more important for paving the wearing layer. The frequency of the pressure beam and the pressure beam oscillate up and down under the drive of pulse hydraulic flow. This pulse is generated by a rotating distribution valve installed on the screed, with a frequency between 58 and 68 Hz. The hydraulic cylinder drives the pressure beam for the entire paving width. After the pulse ends, the pressure beam returns to its original position under the push of the reverse spring. The pulse pressure acting on the pressure beam determines the stroke of the pressure beam.
